Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

3. Devices are ESD sensitive. Handling precautions recommended. Human body model 1.5k

in series with 100pF.

4. Specification for packaged product only.

5. The VTT voltage accuracy is measured as a delta voltage from the reference output (VTT - VREF).

6. Shutdown current is measured only on the VCC pin. The VDDQ pin will always draw a minimum amount of current when voltage is applied.

7. Start-up time is defined as the amount of time from EN = VCC to HSD = 90% of VCC.
